Evaluation Metrics.
We report mean accuracy and mean IOU for semantic segmentation experiments and overall accuracy for image classification following previous works [1]}, [2]}, [3]}, [4]} on these datasts. We note that both mean accuracy and mean IOU are important metrics for semantic segmentation. While a good mean IOU indicates a balanced performance of precision and recall, mean accuracy is an indicator of the detection rate of each class, which is important for safety-critical applications such as self-driving.
